C#進行Visio二次開發之圖紙縮放操作的實現(2)

接著我們實現SetZoom函數，該函數除了接收各種縮放比例外，還可以接收自定義的比例處理。具體邏輯，看代碼後就一目了然

private void SetZoom(string zoomText)
{
switch (zoomText)
　 {
case "400%":
VisApplication.DoCmd((short)VisUICmds.visCmdVIEw400);
　break;
case "200%":
VisApplication.DoCmd((short)VisUICmds.visCmdVIEw200);
break;
　 case "150%":
VisApplication.DoCmd((short)VisUICmds.visCmdVIEw150);
break;
case "100%":
VisApplication.DoCmd((short)VisUICmds.visCmdVIEw100);
break;
case "75%":
VisApplication.DoCmd((short)VisUICmds.visCmdVIEw75);
break;
case "50%":
　VisApplication.DoCmd((short)VisUICmds.visCmdVIEw50);
break;
　 case "上次":
VisApplication.DoCmd((short)VisUICmds.visCmdZoomLast);
break;
　case "寬度":
VisApplication.DoCmd((short)VisUICmds.visCmdZoomSingleTile);
　break;
　 case "頁":
VisApplication.DoCmd((short)VisUICmds.visCmdZoomPageWidth);
break;
case "縮放":
　VisApplication.DoCmd((short)VisUICmds.visCmdVIEwCustom);
　　break;
　 default:
CustomedSize(zoomText);
　 break;
　 }
}
private void CustomedSize(string zoomText)
　　{
　　try
　 {
　 double zoomSize = Convert.ToDouble(zoomText.Replace("%", ""));
　 this.VisWindow.Zoom = zoomSize / 100;
　this.tsStandard_Zoom.Text = zoomSize + "%";
　　 }
catch
　 { }
}

這樣就可以完整實現Visio中的縮放、自定義縮放等功能了。
